The 19% in Germany isn't really import tax, it's VAT.

Import tax, as it has been mentioned before, is probably 0% for European customers. (I'haven't had it checked yet, I'll post details as soon as I get concrete answers.)

You buy your bASIC in the US without tax as well, or am I missing something here: EX TAX: $1,069.99?

If you have a company and buy your ASIC's you can reclaim the VAT so it's a zero sum game, although you'd have to check out how and as what you declare potential profits with mining in your country and what the goverment will get from your profits.

That's something for your accountant and lawyer to figure out as this varies from country to country.
